lumen of trachea. An anatomical space that surrounded_by a trachea.

What is an esophageal tracheal dual lumen airway?

The Esophageal/Tracheal Double Lumen Airway (ETDLA) or Combitube is a secondary option to endotracheal intubation in providing a method of ventilating patients who are unconscious, apneic and pulseless. The ETDLA does not require direct visualization of the airway or significant manipulation of the neck.

What is a PTL airway?

The PTL airway employs a two-tube, two-cuff system that is inserted in a “blind” fashion. The airway’s design allows it to function as an endotracheal tube if the trachea is entered or as an esophageal obturator airway (EOA) if the esophagus is intubated.

When would you use a Combitube?

The Combitube has been used effectively in cardiopulmonary resuscitation (11,14,15). It has been used succesfully in patients with difficult airways secondary to severe facial burns, trauma, upper airway bleeding and vomiting where there was an inability to visualize the vocal cords (9,10,12,13).

What is the function of the lumen in the trachea?

The trachea is lined with a moist mucous-membrane layer composed of cells containing small hairlike projections called cilia. The cilia project into the channel (lumen) of the trachea to trap particles. There are also cells and ducts in the mucous membrane that secrete mucus droplets and water molecules.

What is the purpose of the tracheal gland?

These secretory cells and the glands in the submucosa provide the mucous layer that covers the tracheal epithelium, maintains moisture and traps foreign particles and pathogens. Moving in a coordinated fashion, the cilia are able to transport the mucus orally at a rate of 1.6±0.24 cm/min.

When would you use a dual lumen airway?

Esophageal-Tracheal Double-Lumen Airways. These devices can be encountered in patients who have required airway management in the prehospital setting, such as in trauma or cardiac arrest. The Combitube (Fig. 49.14) is a double-cuff, double-lumen tube.

How does Laryngeal Mask Work?

A laryngeal mask airway (LMA) is a device inserted into the area behind the mouth and nose, connecting them to the food pipe (the pharynx) to allow ventilation, oxygenation, and administration of anesthetic gases, without the need for inserting a tube in the windpipe (endotracheal intubation).

Where is the pharyngeal tracheal lumen airway located?

The device is inserted blindly into the oropharynx and passes either into the trachea or the esophagus. Synonym (s): esophageal tracheal airway, pharyngeal tracheal lumen airway.

How does air flow through the esophageal trachea?

Insertion usually results in esophageal placement ( Fig. 35-3 ), and ventilation is initiated through the gastric lumen. 272 With both cuffs inflated, ventilation through the proximal lumen allows airflow through eight oval fenestrations from the hypopharynx into the trachea.
